We know that Frank is 1/4 Dana's age, so if Frank is represented by f, and Dana is represented by d, then the equation would be
1/4d = f
<span>Secondly, we know that Neil's age is one-half the difference between Dana's and Frank's ages. Because of we learned that Frank is a fraction of Dana's age, we can infer that he is younger than Dana. So, if Neil's age is represented by the variable n, then the equation would be
1/2(d - f) = n
Finally, if we know that Dana is 16 years old, we can find out the other siblings ages using the equations we made above.
d=16
1/4d = f
1/4(16) = f
4 =f
</span>1/2(d - <span>f) = n
</span>1/2(16-4) = n
1/2(12) = n
6=n
Therefore, Frank is 4 years old and Neil is 6 years old.
Answer:
4.5
Step-by-step explanation:
Let the number be x
6x-14 = 40
Add 14
6x = 40+14
6x = 54
Divide by 6
6x/6 = 54/6
x = 9
We want 1/2 of the number
1/2 of 9 is 4.5
